A lot of the “fun” of the site is often trying to figure out why politicians were concerned enough to delete a tweet.

Kevin McCarthy, House Majority Whip, retweeted @ChelsiePaulson tweeting: “You know you’re a huge nerd when you get excited about your monthly Google Account Activitiy Report.” But a day later, McCarthy apparently thought better of it and deleted the tweet.

Was he concerned about losing the nerd vote?

Others’ tweets were deleted after a politician’s twitter account had been hacked.

“Dear Iowans, vote against ACTA, SOPA, and PIPA, because this man, Chuck Grassley, wants YOUR internet censored and all of that BS,” Tweeted the account of U.S. Senator Chuck Grassley.

“I will not celebrate 8.3% unemployment. We need bold leadership & @bararkobama is not up to the task. Join us!”

Apparently, it took The presidential hopeful 2 hours to notice that he’d misspelled the name of the actual president.

The website is produced by the Sunlight Foundation, a nonprofit that has created a number of online tools aimed at creating transparency in government.
